‘No credentials were found in the store’ error is thrown from iOS Auth0 SDK while trying to refresh Token.
This is a random issue. Not able to reproduce the actual scenario for this. But Observed Server logs for this issue happening for multiple users.

Code is as below

        let publisher = self.credentialsManager.credentials(minTTL: Constants.minimumTTL)
            .map { [weak self] _ in
        
                Log.authentication.info("auth - refresh token successful")
                return true
            }
            .mapError { [weak self] error in
                self?.credentials = nil
                Log.authentication.error("auth - refresh token failed: %@", error.debugDescription)

            }
            .receive(on: DispatchQueue.main)
            .handleEvents(receiveCompletion: { [weak self] _ in

            })
            .share()
            .eraseToAnyPublisher()

The response block comes with enum .noCredentials and message “No credentials were found in the store”
